A DCS measurement in a closed glass crucible showed small exothermal effects in the temperature range of 175 -195°C, and endothermic effects in the range of 40 -95°C and 95 -120°C with an onset of app. 106°C (most likely boiling).

The vapour pressure was determined in a temperature range of 31 – 103°C and extrapolated to 20, 25 and 50°C.
